The GEMÜ 520 actuated globe and control valve is available in smaller nominal sizes DN 32, 40 and 50. GEMÜ 520 is suitable for use as a control valve for steam, air, water and process lines on account of its membrane actuator.

The existing sizes DN 65 – 150 are now extended to smaller nominal sizes DN 32 – 50. New actuator/valve body versions have also been developed to further increase the range of applications. In sizes DN 32 – 65 the valve can now be used with up to 40bar operating pressure with valve bodies in cast steel GP 240 H and stainless steel 1.4408.

Further new options include valves which can be actuated with a considerably reduced control pressure of 1.5 – 4bar, depending on nominal size and operating pressure. The matched GEMÜ range of autoset valve positioners provide complete throttling control via PLC or on-board process controllers.
